Golf club head weighting device

The present invention relates to a counterweight device, and more particularly to a counterweight for a golf club head.

Referring to Fig. 1, the Republic of China Announcement No. M265079, "Modified Structure of Weighting Bolts for Golf Club Heads", uses a weighting bolt 11 of different weights to adjust the position of the center of gravity of the golf club head 100.

By replacing the bolt 11 locked in the screw hole 101 of the golf club head 100, although the position of the center of gravity of the golf club head 100 can be changed, the screw hole is to be machined on the irregular golf club head 100. 101, not only is complicated in processing, but also needs to reserve an additional processing amount in order to drill the screw hole 101.

In order to improve the above-mentioned shortcomings, the relevant industry has developed the invention patent of "the weight of the golf club head" No. I444215 of the Republic of China as shown in Fig. 2, and the main improvement is that the weighting bolt 12 is used to drive the pressing member 13 The movement between the pressing position and the non-tightening position eliminates the need to form a screw hole on the golf club head 100, thereby reducing the processing cost and the processing time, but the overall structure is complicated, and therefore, the assembly is time consuming. It is laborious, and the weight device is only embedded on the golf club head 100, so it lacks a firm bonding force and is therefore inferior in stability.

Accordingly, it is an object of the present invention to provide a weighting device that is more time- and labor-saving, and that is easy to use and that incorporates a high degree of stability.

Thus, the weight device of the golf club head of the present invention comprises a weight member detachably disposed on a golf club head, and an adjustment unit cooperating with the weight member.

The weight member includes a head portion and two limiting portions that are spaced apart and integrally protruded from the head portion. The adjusting unit includes an adjusting bolt extending through the head, and a pressing member screwed to the adjusting bolt and located between the head and the limiting portion.

Rotating the adjusting bolt can drive the pressing member to move along the limiting portion between a pressing position and a non-tight position. When the pressing position is in the pressing position, the pressing member is matched with the head. Located at the golf club head, the pressing member is spaced from the head when in the non-tightened position.

The effect of the invention is that directly combining the adjusting unit and the weight member can not only reduce the number of parts to reduce the cost, but also reduce the man-hour required for subsequent assembly, thereby achieving the effect of saving time and labor. In addition, by using the pressing member to cooperate with the head to form the golf club head, the bonding force can be further improved to improve the bonding stability.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figures 3 and 4, a first embodiment of a weighting device for a golf club head of the present invention includes a weight member 2 and an adjustment unit 3 that cooperates with the weight member 2. The weight member 2 includes a head portion 21 and two limiting portions 22 which are spaced apart and integrally protruded from the head portion 21.

The head portion 21 has a cylindrical head portion 211 and a neck portion 212 extending linearly from the head portion 211. The limiting portion 22 extends from the neck portion 212 in a direction opposite to the head portion 211. The projected area of the neck section 212 in the axial direction is smaller than the projected area of the head section 211 in the axial direction.

The adjusting unit 3 includes an adjusting bolt 31 extending through the head portion 21 and a pressing member 32 screwed to the adjusting bolt 31 between the head portion 21 and the limiting portion 22. The adjusting bolt 31 has a screw head 311 that can be received in the head portion 21, and a neck portion 212 extending outward from the screw head 311 and protruding the head portion 21 and partially exposed between the limiting portions 22 Screw 312. The pressing member 32 is screwed to the screw 312.

Referring to Figures 4 and 5, and reviewing Figure 3 together, in practical application, the weight device is embedded in a golf club head 200 having a structure that can cooperate with the weight device. At this time, the pressing member 32 is located at a non-tight position spaced apart from the head portion 21 as shown in FIG. Thereafter, the adjusting bolt 31 is rotated to enable the pressing member 32 to abut against the limiting portion 22, and the rotation of the adjusting bolt 31 is converted into a linear movement along the longitudinal direction of the screw 312, thereby causing the forced The tightening member 32 is moved from the non-tight position shown in FIG. 4 to the head portion 211 of the head portion 21 shown in FIG. 5 to be positioned at the pressing position of the golf club head 200.

By adopting the design that the adjustment unit 3 is directly combined with the weight member 2, not only the number of parts can be reduced to reduce the cost, but also the man-hour required for subsequent assembly can be reduced, thereby achieving the effect of saving time and labor. Further, the head portion 21 having a large area and weight in the weight member 2 can be positioned at the bottom of the golf club head 200, and the effect of lowering the center of gravity can be further achieved. In addition, by using the pressing member 32 to cooperate with the head portion 21 to be located at the golf club head 200, the bonding force can be further improved to improve the overall joint stability.

Referring to Figure 6, a second embodiment of the weight apparatus of the golf club head of the present invention is generally similar to the first embodiment, with the difference that the neck section 212 is integrally tapered from the head section 211. Since the present embodiment is substantially similar to the first embodiment, in addition to the same effect as the first embodiment, the neck segment 212 integrally extended by the head segment 211 can provide a guiding effect. In order to fit the weight device relatively smoothly into the golf club head 200.

In summary, the weighting device of the golf club head of the present invention directly combines the adjusting unit 3 and the weight member 2, thereby not only reducing the number of parts to reduce the cost, but also reducing the man-hour required for subsequent assembly, thereby achieving Save time and labor. In addition, by using the pressing member 32 to cooperate with the head portion 21 to form the golf club head 200, the bonding force can be further improved to improve the bonding stability, so that the object of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
